Description
Technical field
The invention belongs to automotive wiring harness bracket technical fields, and in particular to a kind of wire harness bracket foam process.
Background technique
Currently, well known automotive wiring harness bracket is injection mould die sinking production, unit price is at high cost.Assembling is also artificial group
, often there is the generation of the problems such as position inaccurate in dress.Well known wire harness bracket material is PA66, and wire harness bracket does not have preferable drop
The effect of making an uproar property and waterproof and oilproof.
Summary of the invention
The purpose of the present invention is to provide a kind of wire harness bracket foam process, are positioned with solving wire harness bracket in the prior art
Inaccuracy, and wire harness bracket does not have good noise reduction and poor waterproof oil-proof result technical problem.
In order to achieve the above objectives, the technical scheme adopted by the invention is that: a kind of wire harness bracket foam process, including following
Step:
Technological preparation: the A material of polyurethane is separately added into foaming machine with B material, according to the shape and size of target wire harness bracket
The molding cavity mold group on foaming machine is adjusted, harness is cleared up, mold prepares；
Harness is fixed: the position of mounting bracket to be fixed in foaming machine forming cavity harness, foaming machine fixed mechanism clamping line
Beam；
Installation attachment: the attachmentes such as metallic framework, metal steel ring are installed as requested to the product for having attachment；
It is poured: adjustment pouring temperature, A material and B material is intracavitary by mixing head of foaming machine injection foaming mould；
Curing molding: the intracavitary A material of foaming mould and B expect the voluntarily curing molding under defined mold temperature, are tentatively shaped to mesh
Mark the shape of wire harness bracket；
Demoulding: the male model of foaming machine, master mold are separated, product is taken out；
Deburring: the extra edge grinding of product is trimmed；
Post curing: it by the harness of the subsidiary wire harness bracket to have foamed to after carrying out post curing at room temperature, can be packed and stored.
Mold preparation include by mold cleaning it is clean after, release agent is uniformly coated on mold with hairbrush or spray gun
It is interior.
The adjustment pouring temperature includes by mold temperature control at 40 ~ 55 DEG C, and A material and the control of B material temperature degree are 20 ~ 35
℃。
The curing molding time is 3 ~ 5 minutes.
The demoulding comprises the concrete steps that: first exhaust with mould interface side hand or tool separates product and demould afterwards,
The product hand or tool that have attachment will be reached at attachment notch, attachment and die slot on product is disengaged, slowly hold out
Product.
The time of the post curing is 20 minutes.
Compared with prior art, advantageous effects of the invention:
(1) wire harness bracket foam process of the present invention, the wire harness bracket accurate positioning produced, convenient for improving automation journey
Degree；
(2) wire harness bracket foam process of the present invention, using polyurethane material, cost is relatively low, the line of polyurethane material production
It is preferable that bundle branch frame has preferable noise reduction, Water-proof and oil-proof effect.
Specific embodiment
The invention will be further described below.Following embodiment is only used for clearly illustrating technical side of the invention
Case, and not intended to limit the protection scope of the present invention.
Polyurethane material is used in wire harness bracket foam process of the present invention, therefore the bracket come out that foams has more preferably
Anti-acoustic capability.The A material and B material of polyurethane are two kinds of components of synthesis of polyurethane product, and A is isocyanate component；B is polynary
The assembly that other pure and mild small powders are matched.
Wire harness bracket foam process of the present invention, process flow include technological preparation, harness fix, install attachment,
Casting, curing molding, demoulding, deburring, post curing.
Technological preparation: the A material of polyurethane is separately added into foaming machine with B material, harness is cleaned out, according to score
The shape of bundle branch frame and the molding cavity mold group on size adjusting foaming machine clear up foaming mould, with hairbrush or spray gun by release agent
It is uniformly coated in mold, release agent is used in an interface coating of the body surface that two are easy to adhere each other, it can make
Body surface is easy to be detached from, is smooth and clean, and coated release agent is conducive to the smooth disengaging of shaped article and mold in mold.
Harness is fixed: the position of mounting bracket to be fixed in foaming machine forming cavity harness, foaming machine fixed mechanism folder
Stringing beam.By injection molding on wire harness bracket direct-on-line beam in foaming mould, harness assembling production on the one hand can be improved
The degree of automation, product on the other hand can be made to have better dust-proof, Water-proof and oil-proof effect.
Installation attachment: the attachmentes such as metallic framework, metal steel ring are installed as requested to the product for having attachment, it is desirable that: position
Accurately, specifications and models are correct.
Casting: by mold die temperance control at 40 DEG C ~ 55 DEG C, by A material and the control of B material temperature degree at 20 DEG C ~ 35 DEG C, foaming mould
The pressure and temperature of die cavity is relatively low, reduces the relative requirement to mold, and the design of foaming mould can be made more flexible, thus
To reduce the mold opening cost of new stent in existing design, manually installed bracket position inaccurate generation is avoided the problem that.By A material and
B material is intracavitary by mixing head of foaming machine injection foaming mould.
Curing molding: the intracavitary A material of foaming mould and B expect voluntarily curing molding, first one-step forming under defined mold temperature
For the shape of target wire harness bracket, 3 ~ 5 minutes molding time is generally cured.
Demoulding: foaming machine male model master mold is separated, when product in stripper member, first exhaust, after connecing product and mold
Mouth side hand or tool are separated and are demoulded, and have to handle to the product for having attachment or tool reaches at attachment notch, make product
On attachment and die slot disengage, slowly hold out product, prevent product from tearing.
Deburring: the extra edge grinding of product must be trimmed, trimming must be neatly without zigzag.
Post curing: by the harness of the subsidiary wire harness bracket to have foamed to progress post curing 20 minutes or so at room temperature, i.e.,
It can be packed and stored.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations
Also it should be regarded as protection scope of the present invention.
